HMC680LP4 Description

The HMC680LP4(E) is a digitally controlled variable gain amplifier which operates from 30 to 400 MHz, and can be programmed to provide -4 dB to +19 dB of gain, in 1 dB steps. The HMC680LP4(E) delivers noise figure of 5 dB in its maximum gain state, with output IP3 of up to +40 dBm in any state. This high linearity DVGA also provides a differential RF output which can be used to interface directly with SAW filters in Tx and Rx applications, and with digital to analog converters in Rx chains. The HMC680LP4(E) is housed in a RoHS compliant 4x4 mm QFN leadless package, and is CMOS/ TTL compatible.
